Streak Calculator: How Often Runs Turn Up
A run of one colour looks like a message, yet a long strip of rounds holds runs by arithmetic alone. Type a chance, a number of rounds and a run, and read the exact chance it turns up somewhere. It opens on 4 in a row in 60 rounds.
A streak, or run, is the same result several times in a row. The box above opens on a colour that comes up 40 times in 100, a stretch of 60 rounds and a run of 4. The 40% is an illustration, because at the time of writing (8 October 2026) we could not read Shree Win’s Win Go rules. Sixty rounds is an hour only if each round takes a minute, and we do not know its round lengths. Change every box to match your own screen.
Words on this screen
| Box or tile | Plain meaning |
|---|---|
| Chance each round goes your way | How often your result comes up, such as a colour at 40% |
| Rounds in the stretch | How many rounds the strip you are looking at covers |
| Run you are asking about | How many in a row |
| Which runs count | Only your outcome, or your outcome and its opposite, as with big and small |
| 1 in 610 | The chance that seven named rounds, picked in advance, all go that way |
| Longest run to expect | The length that half of all stretches reach |
Seven reds: two different questions
“How rare is seven in a row?” can mean two things. Pick seven rounds before you start, and all seven coming up red is 1 in 610. Ask instead whether seven reds appear anywhere in the strip, and the answer depends on how long the strip is.
| Stretch (one-minute rounds) | Rounds | Seven reds somewhere | Longest red run to expect |
|---|---|---|---|
| An hour | 60 | 5.3% | 4 |
| Two hours | 120 | 11% | 5 |
| Four hours | 240 | 21% | 5 |
| A day | 1,440 | 76% | 7 |
The leap from 1 in 610 to 76% is the whole lesson. A long strip has many places where a run can begin, and each one is a fresh chance.
Big or small: either side counts
With two sides at 50% each, a run of seven alike is far more common, because either side can make it.
| Stretch (one-minute rounds) | Rounds | Seven alike, big or small | Longest run to expect |
|---|---|---|---|
| An hour | 60 | 36% | 6 |
| Two hours | 120 | 61% | 7 |
| Four hours | 240 | 86% | 8 |
| A day | 1,440 | over 99.9% | 11 |
So a four-hour strip of big and small results holds a run of seven more often than not, and it needs no explaining.
After a run
The round after a run keeps the chance you typed: 40% for red, whether the last seven were red or not. The tool prints that under its result. Rounds do not remember.
Two other numbers help. For seven reds the tool says 706 rounds until a run is more likely than not, and 1,016 rounds on average before the first one. Long runs also thin out quickly. In a day of 1,440 rounds, a run of 8 reds turns up in 43% of strips, 10 in 8.6% and 12 in 1.4%.
One more thing to keep in mind: a strip with a run in it is the strip you stopped to look at. The ones without a run did not catch your eye.
Checking your own strip
- Count the rounds the strip covers and type them as the rounds in the stretch.
- Type the chance of your result. Use what your screen states; we could not read it for any Shree Win tile.
- Type the run you can see.
- Choose “only your outcome” for one colour, or the either-side choice for big and small.
- Press the draw button to watch 1,000 pretend stretches test the figure.
A worked example: your strip covers 90 rounds and shows 6 reds in a row. Type 40, 90 and 6, and the tool says 19%, about 1 strip in 5, with 4 as the longest run to expect. That is a little long, and still ordinary.
What it cannot tell you
The calculator assumes every round is a fresh draw with the chance you typed. It does not know how any platform makes its results, and we cannot see inside one, so a run on your strip is not evidence in either direction. For a whole pasted list, the colour history checker tests runs and counts together, and the hack guide explains why a streak cannot predict the next round. The Win Go guide describes the round, and the tools page lists the rest.

Common questions
A friend says seven in a row happens once in 610 rounds. Is that right?
Not quite. 1 in 610 is the chance that seven rounds named in advance all go one way. Counting every place a run could begin, the average wait for the first run of 7 reds is 1,016 rounds, and half of all stretches have shown one by round 706. The two figures answer different questions, and the tool prints both.
How many rounds should I type for a whole day?
It depends on the round length of the tile, which we could not read for Shree Win. If a round comes every minute, a day holds 1,440. Every 30 seconds gives 2,880, every 3 minutes 480 and every 5 minutes 288. Look at the lengths your own tile offers and multiply.
Why does the longest run to expect grow so slowly as the strip gets longer?
At a 40% chance, each extra step in run length needs about 2.5 times more rounds before it turns up: 282 rounds for a run of 6, 706 for 7 and 1,764 for 8, counting until it is more likely than not. So the longest red run to expect is 4 in 60 rounds, 5 in 120 and 7 in a day of 1,440. A run of 15 reds in that day turns up in 0.09% of strips.
What do I type for violet, or for one number?
The chance your own screen states. Rounds of this kind are commonly described with violet on 2 digits of 10 and one number on 1 digit of 10, which are 20% and 10%, but we could not read Shree Win’s rules. At 20%, three violets in a row turn up somewhere in 60 rounds in 32% of strips. At 10%, three of the same number in 1,000 rounds turn up in 59%.
Can a long run mean the results are not random?
Not on its own. A run of 7 reds turns up in 76% of day-long strips, and a run of 10 in 8.6%. A run of 15 would turn up in about 0.09% of them, which is worth recounting before you read anything into it. Even then the tool cannot say why, and we cannot see inside any platform.
What does the “Draw 1,000 random stretches” button do?
It makes 1,000 pretend stretches of the length you typed, using your browser’s random numbers, and counts how many hold the run. The count lands close to the exact figure, which shows the figure is what random rounds do. There is no money in it, nothing is saved, and it is not any platform’s game.
